Performance-wise, it can stutter a bit on modern websites and sometimes in some apps, but otherwise works reasonably well. A few weeks ago I noticed it was struggling more than usual and chewing up more battery, but then I cleared up some disk space and it's been running fine.
The minimum supported iOS version for some of my must-have apps (e.g. WhatsApp, my banking app) is currently iOS 15, so I imagine when that changes I'll need to finally upgrade my phone. Feels like its days are numbered.
Was hoping for the new iPhone Fold (with Touch ID even) to be small but looks like it’s going to be a really weird ratio when folded.
Of course there are caveats: - Spotify not getting app updates anymore (but still playing fine)
- some websites do not support the Safari version, e.g. GitHub
- most banking apps are not supported
